Well guys today was the first time my truck has ever seen single digit MPG. 7 to be exact! It was also the hardest the truck had worked in its life. Coming home from Oklahoma today with a 40MPH head wind through the flint hills pulling a 28 foot brick of an enclosed trailer loaded to the gills is not good on the wallet tried to maintain 65, there was a period where I had to stay in 4th for a solid 30 minutes at around 2600 RPM. I thought she was going to blow but she held together!

Anyways I'm just excited....

What's the worst you guys have ever gotten?

BTW I usually get around 10.5 on the same route with that trailer, 11.5 on flat ground.

According to my lieometer pulling over the grapevine in so cal. I hit 4.2mpg, I would say I average about 9.5mpg. I try to not pay attention, my best is 11.6mpg, I dont tow any faster than 62mph as my mileage will really drop.

I got about 7 mpg a few years ago when the truck was stock trying to pull a very heavy toyhauler through very strong headwinds and up hill most of the way. I was ready to take the truck back that day, I was so frustrated. The funny part is that it was my friend's toyhauler and he was so impressed by the power that he went out two weeks later and bought a 6L Excursion to replace his suburban. Here I was completely frustrated and disgusted with my truck and he was floored because he thought it was amazing. It's amazing how people see things differently!

Coming back to Dallas last week from McAllen I hit a head wind that was so strong that the truck dropped to 3rd gear and would only run about 58 MPH for about 4 or 5 miles.
My truck likes to pull the fifth wheel at 67 to 72. When there is no wind and no hills it's hard to keep it below 70 mph. So I know what you mean about 70 to 75 with your truck and trailer. Most of the time I get 9.5 to 10.3 pulling.
